STEAM-CONDENSER AND WATER-HEATER.

SPECIFICATION forming part of Letters Patent No.434,463, dated August 19, 1890.

Application filed February 10, 1890. Serial No. 339,918. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANK RADEMACHER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Steam-Condensers and Tater-Heaters, of which the following is a specification.

v One object of my invention is to so construct and arrange the parts of the condenser and heater as to reduce to a minimum the ill effects of the contraction and expansion,and to do this by simple inexpensive means.

A further object is to insure great efficiency in the heater,so that the water will be rapidly heated and the steam condensed with corresponding rapidity.

A further object is to secure convenience of access for repair.

The general construction and arrangement of parts are briefly described as follows: My improved heater and condenser comprises the combination of a water-ingress compartment, a water-egress compartment, a steam-receiving compartment located between such ingress and egress compartments, a base or settling compartment located beneath such ingress and egress compartments, a steam-condensing chamber communicating with the steam-receiving compartment and located between the base-compartment and the ingress and egresscompartments, surface tubes passing through such steam-condensing chamber and connecting the ingress-compartment with the base-compartment, surface tubes passing through such condensing-chamber and connecting the base-compartmentwith the egresscompartment, an ingress water-pipe opening into the ingress-compartinent, an egress water-pipe opening from the egress-compartment, a steam-pipe opening into the steamreceiving compartment, and a condense-waier pipe leading from the condensing-chamber. This construction and various details are illustrated in the accompanying drawings, in which Figure 1 is a vertical mid-section along line 90 00, Fig. 3. Fig. 2 isa vertical mid-section at right angles to that of Fig. 1. view. Fig. 4 is a plan view, partly in section Fig. 3 is a topand with the top removed. Fig. 5 is a view of the inner side of one of the top shells.

The body of the heater and condenser is formed of the barrel or drum A, having two semicircular sheets B B at the top and a circulartube-sheet O at the bottom. The straight edge I) of each of the top tube-sheets B B is bent upward and is secured, respectively, to partition-sheets D D, which form the side Walls of the ingress steam-compartment E, which extends across the dome of the heater. The dome ofthe heater and condenser is formed of the two concave top shells F F and the cap-piece G. The cap-piece G forms the top of the ingress steam-compartment, and the shells F F form, respectively, the tops of the water-ingress and water-egress compart ments. The floors of the ingress and egress water-compartments are formed, respectively, of the top tube-sheets Band B.

The bottom tube-sheet 0 forms the bottom of steam-condensing chamber 11 and the top of settling or base compartment I. The surface tubes J pass through and are secured to the top sheet B and bottom sheet O and connect the ingress-compartment with the basecompartment. The surface tubes J pass through and-are secured to the top sheet B and bottom sheet O and connect the base-compartment with the egress water-compartment.

K is the cold-water-ingress pipe.

L is the hot-water discharge or egress pipe.

M is the steam-pipe, which passes through a stuffing-box N in the top shell or wall F of the ingress-compartmen t, through the wateringress compartment, and through the partition-sheet D, in which it is fastened, and opens into the ingress steam-compartment E.

The steam-pipe M is secured to the partitionsheet D near the center thereof, and the steam entering through it strikes upon the center of the opposite partition-sheet D and rebounds against D, thus heating the sheets forming walls D D more intensely at the centerthan elsewhere, so that the effect of the expansion is to bulge the sheets and not to strain the shell or the tube-sheets of the heater. A degree of play of. the top tubesheet is provided for, however, to compensate for the expansion and contraction of the tubes tubes J.

J J. To allow for such expansion and contraction, the top sheet is formed of the two sections 13 B disconnected from each other, and further allowance for expansion and contraction is made by leaving a space around the tubes in both the top and bottom tubesheets between the tubes and the flanges 0, between which the sheets are clamped.

'lhe eold-water-ingrcss pipe K is located axially over the steam-pipe M, so that the discharge of the cold water is directly against the steam-pipe, whereby the water is heated and the steam is cooled in a degree before the steam has entered the compartment E. The water from pipe K strikes upon steanr pipe M, and is thereby distributed so that it will flow more equally through the several The cold water passing through F is heated by the steam in pipe M and that in compartment E and condense-chamber II, thereby raising the temperature of the water before it is allowed to enter the tubes J. By this means I avoid the ill efiects of expansion and contraction, which result when the cold water is allowed to [low immediately into long surface tubes.

The tubes J, base-eompartmentI, and tubes J form a conduit connecting the ingress and egress compartments for the passage of th e water, and as the water flows on through the tubes J and J it is further heated by the steamin H, and when it finally reaches the egress-compartment it receives the heat from the direct blast of steam against partition-sheet D, so that it receives the greatest heat just before discharging. a

The base-coinpartment I serves as a settlingchamber, and the sediment can be removed from time to time through the hand-hole P. The condense-water is led off through pipe Q, which passes through a stuffing-box R to allow longitudinal movement of the pipe during its expansion and contraction.

'lo repair the heater, access is given to the interior by removing the nuts T from bolts S, thereby allowing the removal of the base U and top.

Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a heater and condenser, the combination ofthe water-ingress compartment, the watier-egress compartment, the steam-reeeiving compartment located between the water 1ngress and egress compartments, the base-compartment located beneath such ingress and egress compartments, a steam -condensing chamber communicating with the steam-receiving compartment and located between the base-compartment and the ingress and egress compartments, surface tubes passing through such steam-condensing chamber and connecting the ingress compartment with the base-compartment, surface tubes passing through such condensing-chamber and connecting thebase-compartment with the egresscompartment, an ingress Waterpipe opening into the ingress-compartment, an egress water-pipe leading from the egress-compartment, a steam-pipe opening into the steam-receiving compartment, and the condense-water pipe leading from the steam condensing chamber.

2. In a heater and condenser, the combination of a water-ingress compartment, a wateregress compartment, a conduit connecting the ingresscompartment with the egress-compartment, a steam-receiving compartment between the ingress and egress compartments, a stu'lfing-box in the wall of the ingress-compartment, a steam-pipe passing through such stui'fing-boxand through the ingress-compartment and opening into the steam-receiving chamber, the water-ingress pipe located axially over such steam-pipe, and the dischargepipe leading from the egress-compartment.

3. In a heater and condenser, the combination of the cold-Water-ingress compartment and a water'ingress pipe opening thereinto, tubes leading therefrom, a stufling-boxin the walls of such compartment, and a steam-pipe located between such pipe and tubes in the line of discharge of such ingress-pipe and passing through the stufling-box.

4. The combination of the barrel, the demo, the partition-walls, the two semicircular top tube-sheets, the bottom tube-sheet, the base, the surface tubes, and the ingress and egress pipes.
